Lake was not only beneficial to grazing firewood and green manure, but also conducive to the reproduction of grass-laying fish sand the growth of herbivorous fish.
"We hope to establish a comprehensive, systematic and authoritative database, which is also long-term based and dynamic, to solve the natural and social problems facing Poyang
Lake, and to realize sustainable development in the region," Hu said.
Xinhua said about 63 percent of the Yangtze cowfish live in Poyang
Lake and the Jiangxi section of the river, but a Jiangxi water quality official said he had never heard of any in the lake.
However, these previous research mainly focused on particular hotspots, such as the Ramsar Sites or nature reserves at a local scale (e.g., Dongting Lake, Poyang
Lake, and the Jianghan floodplain, etc.) hence; the conservation strategies were generated based on local and site-based protection and cannot adequately be used as guidelines for a broad-scale conservation initiatives for freshwater wetlands across Central Yangtze Ecoregion.
The report said the recent finding of 4,004 white-naped cranes at Lake Poyang
, located along the middle reaches of the Yangtze River, will spark a review of estimates put out by the International Crane Foundation (ICF).
Lake is an important overwintering site for migratory birds in Asia.

Lake in recent 60 years," Yangtze River, vol.
C[H.sub.4] fluxes from heavy pollution sites (1#, 2#, 5#, and 8# sites) in our study were close to the Poyang
Lake , Yangtze River estuary , 5 Netherlands lakes , the Bay of Fundy , and the Shrimp pond of Min River estuary  and were greater than those from natural wetlands and less polluted lakes, such as 11 North America lakes , Polegar Lake , Yellow River estuary wetlands , Sparkling Lake , 30 boreal lakes , reservoirs [40, 42], and less polluted sites (3#, 4#-6#, 7#, 9#, and 10# site) in this study.
Rainfall has pushed up water levels above warning levels at the outlets of the Dongting and Poyang
lakes leading to the Yangtze, while many creeks and rivers throughout the country have overflowed.
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is a critically endangered sub-species of the narrow-ridged finless porpoise (Neophocaena asiaeorientalis) that exclusively occurs at Yangtze River and adjacent Poyang
Lake and Dongting Lake (Gao and Zhou, 1995; Jefferson and Wang, 2008).

Lake basin," Theoretical and Applied Climatology, vol.
Torrential rain in southern China has pushed water above warning levels along the Yangtze River as well as on Dongting, Taihu and Poyang
lakes, the ministry said.
